This question of getting the balance right is obviously important
The most typical minimum daily compostable ouput of my household is
probably something like the following:-

1 copy of the The Independent
1 copy of the Evening Standard
4 or 5 tea bags
1 grapefruit peel and pips/1 apple core and pips
4 or 5 litres (? maybe more - never measured it) of "night water".

There will of course be the occasional grass clippings, leaves,
vegetable peelings etc but the above is the reliable minimum daily
output. Can this make good compost?
